Design of all-Optical Transmission Gate Using Silicon Microring Resonator

Abstract

Proposed manuscript includes the implementation of all-optical transmission gate employing silicon microring resonator. A replacement for traditional CMOS technology, large-scale optical integrated circuits are being considered due to the increasing need for ultra-fast terahertz data processing and transfer. In addition, energy-efficient circuits are becoming more and more crucial. The architecture is analyzed at about 260 Gbps using MATLAB. Networks for optical signal processing can be constructed using all-optical transmission gates as building blocks. Proposed transmission gate is also utilized in the design of a 2:1 multiplexer. The evaluation of a few performance-indicating variables includes “extinction ratio (ER)”, “contrast ratio (CR)”, “amplitude modulation (AM)”, “on–off ratio (OOR)”, and “relative eye opening”. At low average pump power of 1.18 mW, proposed model has high ER, CR, and OOR of 26.78, 31.39, and 36.8 dB, respectively. Computed AM is recorded as 0.22 dB. Optimized design parameters are chosen to utilize the design practically.
